The Science
Psy103 - Global warming is a steady increase of the earth’s temperature, which causes change in the climate. A warmer earth can lead too changes in rainfall, a rise in sea level, and a huge impact on our weather, wildlife, and humans. Therefore global warming and its devastating effects are serious threats to the overall present and future health of the planet. Yet it seems that climate conditions in recent years and provide a little more proof then that ever before. Since about 1970 we have seen hotter summers then usual, with the average surface temperature being warmed about 1 degree Fahrenheit. The earth’s surface is currently warming at a rate of about 0.32 degrees Fahrenheit each decade or 3.2 degrees a century. The five warmest years over the last century have likely been: 2005, 1998, 2002, 2003, and 2006. The top warmest years have all occurred since 1990. According to Administrations NASA (2006) Surface Temperature Analysis.
Psy 103 - Rainforests once covered 14% of the earth’s land surface; now they cover a mere 6% and experts estimate that the last remaining rainforests could be consumed in less than 40 years. One and one half acres of rain forests are lost every second with tragic consequences for both developing and industrial countries. According to Rainforest Facts (2007) Res 110
Res110 - In the past centuries, the earth has heated up about one degree in Fahrenheit, which doesn’t seem like much but over the past two decades it has heated up intensely. “For over the past 200 years, the burning of fossil fuels, such as coal and oil and deforestation has caused the concentrations of heat trapping also known as “greenhouse gases” to increase significantly in our atmosphere. Which in turn prevents heat from escaping into space” (Environmental Protection Agency 2007). However the gases are necessary to life because of without them the earth would not be as warm as it needs to be.
